SPECIFICATION forming part of Letters Patent No. 324,986, dated August 25, 1885.

(N model.)

To all whom it may concern.-

Be it known that I, LUTHER C. ORoWnLL, a citizen of the United States. residing in the city of Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Printing-Machines, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

In the publication of newspapers, and particularly of daily newspapers, as it is carried on at the present time, it is of the highest importance to have machinery which will print an entireedition in the least possible time, so that the forms may be kept open for the re oeption of news down to the latest possible moment before the actual issue of the paper. It is also very desirable that this be accomplished by a single machine, and with the least possible duplication of the fol ms.

In the case of many of the larger newspapers ithas become customary to issue papers upon different days which vary greatly in their amount or volume of printed matter.

It therefore, in such establishments, becomes desirable to have machinery which is capable of producing either of several different -sized products. In order, therefore, to meet the wants of those newspapenprinting 3o establishments which issue large editions of a paper, and of sizes which vary with different days, the main object to be attained is the production eta-machine which is capable of producin the greatest possible number of papers 3 5 in the least possible time and in the greatest variety as to size or amount of printed matter.

It is the object of the present invention to provide a machine adapted to meet the wants of the class of printing establislnnents just mentioned; and to that end the invention c011- sists in combinations ofWeb-printing and webturning or turning and associating mechanisms by which a single machine is capacitated k to simultaneously perfect two or more webs with matter for either of a large Variety of products, and direct said webs out of the machine in proper relation to each other to be made up into papers of the desired size by any suitable delivery mechanism, all of which will be hereinafter fully explained and particularly pointed out.

The machine embodying the invention in its most complete form consists of a main printing and web-turning or turning and associating mechanism arranged to perfect and direct out of the machine two main webs, and asupplement-printing and web-turning mechanism arranged to perfect a supplementweb and deliver the same at the same point with the main 6o webs. As, however, the latter may be omit-- ted, the two will be described separately.

In the accompanying drawings, Figure 1 is an elevation of the main printing mechanism as seen from its delivery end. Fig. 2 is aplan or top view of the same and also of the supplementprinting mechanism. Fig. 3 is a plan view of the lower portion of the main mechanism. Fig. 4. is a diagrammatic sectional elevation taken on the line 0000 of Fig. 2, looking toward the supplement-printing mechanism. Fig. 5 is a sectional elevation of the maehine,taken on the line 3 y of the same figure, parts of the frame-work being omitted. Fig. 6 shows the upper main web as printed, split longitudinallyinto two sections, and said sections associated to form eight pages of a twelve page product, and the supplementweb as printed, split longitudinally into two sections, and one of said sections associated with the sections of the main web to form the remaining four pages of said twelve'page product. Fig. 7 is asimilar view of the lower main web and the other section of the supplementweb. Figs. 8 and 9 are longitudinal sectional views of Figs. 6 and 7, respectively. Figs. 10 and 11 show a twelve-page product or paper as formed, respectively, from the transverselysevered sections of said associated sections. Fig. 12 shows the upper main web as printed, split longitudinally into two sections, andsaid sections associated to form eight pages of a ten-page product, and the supplement-web as printed,split longitudinally into two sections, and one of said sections associated with the sections of the main web to form the remaining two pages of said ten-page product. Fig.

13 is a similar view of thelower main web and the other section of the supplement-web. Figs. 14 and 15 are sectional'views of the associated I00 sections of Figs. 12 and 13, respectively, showing the order in which the half-sheet supplements will be associatedwith the full sheets to form the ten-page product. Figs. 16 and 17 show a ten-page product or paper as formed, respectively, from the transversely-severed sections of said associated sections. Figs.'18 and 19 are respectively views of the upper and lower main webs, showing the same as printed, split longitudinally, and having their sections associated to form an eight-page product. Figs. 20 and 21 are longitudinal sectional views of Figs. 18 and 19, respectively. Figs. 22 and 23 show an eight-page product or paper as formed, respectively, from the transversely severed sections of said associated sections. Figs. 24 and 25 show the upper and lower webs, respectively, as printed to form four pages of a six-page product, and the supplement-web printed to form the remaining two pages of said six-page product. Figs. 26 and 27 are sectional views of the webs, showing the order in which the half-sheet supplements severed from the supplement-web will be associated alternately with the full sheets severed from the main webs to form six-page products. Figs. 28 and 29-show a six-page product or paper as formed, respectively, irom the transversely-severed sections of each of said webs. Figs. 30'and 31 show the upper and lower main webs, respectively, as printed to form a four-page product. Figs. 32'and-33 show a four-page product or paper as formed, respectively, from the transverselysevered 'sections'of each of said webs. 'Fig. 34 is a diagrammatic view showinghow the main printing mechanism may be provided with additional impressioncylinders and webturners, so as to simultaneously perfect three or more webs, all containing the same printed matter; and Fig. 35 is a like view showing a modified arrangement of the main and supplement printing mechanisms.

Referring now particularly to Fig. 4,it is to be understood that the main mechanism-i. 6., that, for operating upon the main webs-consists of two groups of printing mechanism, one for printing each side of the webs. As shown in said figure, each of these groups consists of one type-cylinder, as 32 34, two in1- pression-cylinders,as 31 33 and 35 37 ,and suitable inking mechanism. (Represented in the present case by the inking-rolls 36.) It may also be stated that the type-cylinders may be constructed in any of the known ways to carry the types themselves or stereotype or electrotype plates. These type and impression cylinders are mounted on parallel axes in a suitable frame-work, as shown in Fig. 1, and are driven with uniform surface speed in the proper directions by suitable gears, as 83 82 81 87 84 85, by motion transmitted from a main shaft, as 18, through miter'gears, as 69 7O 71 72, or in any other convenient manner. To the printing mechanism thus organized there are led two webs of paper from rolls 100 200, the former of which is supported in the usual manner above or at the side of the printing-cylinders,and the latter between said cylinders, as shown in Figs. 1 and 4. The upper of the two webs of paper is marked A, and the lower is marked B, so that the same may be distinguished wherever they are shown as passing through the machine, and for a like purpose the surface of each web which is first printed is marked a, and the surface which is last printed is marked b. The web A is led from the roll 100 over a leading-roll, 21, and thence to and around the impression-cylinder 31, in passing which it is printed upon its side a by the forms upon the cylinder 32. After being thus printed upon its side a the web passes over a leading-roll, 22, and thence across the machine over a leadingroll, 23, to and around the impression-cylinder 35, in passing which it is printed upon its sideb by the forms upon the cylinder 34. After being thus printed upon its second side the web passes over a leading-roll, 24, and is led thence backward across the machine to and around a leading-roll, 25, in passing which it may be split longitudinally into two sections or narrow webs by a slitter, 60, which is arranged to operate in the usual manner, after which the web, or, when split, the sections are led to and around web-turning or web turning and associating de'vices,by which it or they are either turned or turned and associated so as to be led forward either singly or together at right angles to their previous path of travel and pass laterally outward above a roll, 7 5, located at the side of the machine, as shown in Figs. 2 and 5. The web B is led from the roll 200 under a leading-roll, 26, and thence to and around the impression-cylinder 33, in passing which it is printed upon its side a by the forms upon the cylinder 32. After being thus printed the web passes under a leading-roll, 27, and thence across the machine under a leading-roll, 28, to and around the impressioncylinder 37, in passing which it is printed upon its side I) by the forms upon the cylinder 34. After being thus printed the web passes under a leading-roll, 29, in passing which it, like the web A, may be split longitudinally into two sections or narrow webs by a slitter, (31, which is arranged to operate in the usual manner, after which the Web or sections are lead to and around a set of webturning or web turning and associating devices, by which it or they are either turned or turned and associated so as to be led forward either singly or together at right angles to their previous path of travel and pass laterally outward beneath a roll, 76, located at the side of the machine, as shown in Figs. 2, 3, and 5.

The web-turning or turning and associating devices which operate upon the web A consist of two turning-bars, 40 41, (see Fig.2.) the former of which is of a length sufficient to receive and turn the full web, whether split into cylinders, the latter being arranged parallel with the former in the same or nearly the same horizontal plane, and at such a distance therefrom that when one of the sections of the web is led around each bar the two sections will be brought together one above the other, as shown in Fig. 2, and the two bars being supported by attachment to the frame-work in any suitable manner. The web turning or turning and associating devices which operate upon the web B likewise consist of two turningbars, 42 43, (see Fig. 8,) which are similarly arranged and supported, except that the two pairs of bars are placed at right angles to each other. By locating these turn ng devices between the two sets of printingcylinders,and by arranging them at the relative angle to each otherjnst described, it not only becomes possible to lead bot-h webs laterally outward at the same side of "the machine, but to lead them out in such position with relation to each other that the product of both webs can be manipulated by a single delivery mechanism. The angular position of the bars may, however, vary from that shown, so that the webs may be delivered from them at more or less variance from a right-angular position with respect to the printing mechanism.

It will be observed that, as herein shown, the turning devices and the leading-rolls are so arranged that the web A is delivered from the machine with its side a uppermost,aud the web 13 with its side I) uppermost. By omitting the roll 25 and leading the web Adirectly from the roll 24 to the turning devices it may be delivered with its side I) uppermost, or by leading the web B around a roll located similarly to the roll 25 it may be delivered with its side a uppermost. It will also be seen that, if preferred, the wcbturning devices maybe arranged so that one of the webs will be led laterally outward at each side of the machine.

From the rolls 75 76 the webs orsections of the webs may be led to two independent delivery mechanisms, one for operating upon each web 01' the sections of each web, or they may be led to a single mechanism which shall be capaeitated to receive and dispose of the product of both webs. A mechanism of this latter character is shown and described in my application for Letters Patent filed May 16, 1883, Serial No. 95,068. hen the sections of the two webs are to be operated upon by a single delivery mechanism,they will preferably be led downward and upward, respectively, toa pair of leading-rolls, 58 59, between which they will pass in close proximity to each other, as shown in Fig. 5.

In order to secure the proper register between the printed pages upon the opposite sides of the webs, one or both of the leadingrolls 22 23 and 27 28 may be made adjustable, so as to vary the distance traveled by the webs between the printing of their opposite sides. When the sections of each web are associated, the pages of the two sections may bebrought into register by the use of suitable register rolls, as 105 106 79 and 107 108, as shown in Fig. 5.

The printing mechanism thus far described is, as will be seen, capacitatcd to simultaneously perfect two webs with the same matter and deliver them both at the same point, running in the same direction, and with the same or different printed pages upon their respective upper and under surfaces; and it will also be seen that this is effected without turning or deflecting either of the webs before or between the printing of their opposite sides, and by giving only a single or half turn to each web after the completion of the printin If it is desired to still further increase the capacity of the machine so that instead of two three webs may be sin'iultaneously perfected, the third web being printed with matter different from that upon the other two, the supplementprinting mechanism will be brought into operation, by which a third web may be perfected and delivered at the same point with the two main webs, so that its sheets may be afterward associated with those from the main webs to increase the volume or size of the printed product.

Referring particularly to Figs. 2 and 5, such a supplement-printing mechanism will now be described. This mechanism, as shown in the present case, consists of a single type-cylinder, 50, and two imprcssion-cylinders, 51 52, the shafts of which are mounted in suitable bearings supported by an extension of the frame-work. These cylinders, which are arranged at right angles to the main printing mechanism, are connected by gears 6t (35 66 in the usual manner, and receive motion through any suitable connections, as the gears 67 (38, the latter of which is 011 the shalt of the impression-cylinder 34. The gears 67 68, or other means by which the supplemental printing mechanism is driven, will be so pr0- portioned and arranged that said mechanism may be driven at the same speed as the main printing mechanism, or at a different speed, according to the product which is to be produced, as will be hereinafter more fully explained. This printing mechanism will be provided with suitable inkin apparatus, of which only the inking-rolls 58 are shown. This supplementprinting mechanism is pro vided with suitable leading-rolls and webturning devices supported in a suitable framework above the printing-cylinders, and an ranged to turn over or reverse the web after it has been printed upon one side, so as to permit its unprinted side to be presented to the forms upon the type-cylinder, thereby causing both sides of'the supplement-web to be printed from the same forms. The web-turning devices just referred to consist of two turning-bars, 4st 45, attached to the framework and arranged at right angles to each other, one, 44,being raised sufficiently to admit the passage of the supplement-web between them, and a leading-roll, 91, arranged at right angles to the printing-cylinders, said turning devices being of the construction shown in United States Letters Patent No. 212,444. The supplement-web, which is marked 0, and like the main webs has its surfaces which are first and last printed marked a and b, respectively, is led from a roll (not shown) to and around the impression-cylinder 51, in passing which it is printed upon its side a by the forms upon the cylinder 50. After being thus printed upon its side a it is led around a leading-roll, 90, thence over and downward around the turning-bar 44, thence laterally outward around the roll'9l, thence inward above and downward around the second turning-bar, 45, thence forward around a leading-roll, 92, to and around the second impression-cylinder, 52, in passing which its side b will be presented to and printed by the forms upon the cylinder 50. After being thus printed upon both its sides the web 0 is led around a pair of registerrolls, 93 94, and thence through the main printing mechanism, between the upper and lower web-turning devices, to a leadingroll, 95, in passing which it may be split longitudinally into two sections or narrow webs by a slitter, 96, which operates in the usual manner, after which the webs or sections are led around a roll, 9, and thence outward between the rolls 58 59 below the sections of the web A and above the sections of the web B. The proper register of the impressions upon the opposite sides of the web C may be secured by means of the rolls 90 91 92, one or more of which may be made adjustable, so as to vary the distance traveled by the web between the printing of its opposite sides to secure this result, and the proper register between the impressions upon the web 0 and the webs A B may be secured by means of the rolls 93 94, one or both of which may also be adjustable, so as to vary the distance traveled by the web between the cylinder 52 and the rolls 58 59.

It will be observed that in the embodiment of the invention shown in the accompanying drawings the several type-cylinders are of the same size, each being of a length equal to the length of the two forms for printing the pages of the required product, and of a circumference equal to the width of two such forms, the forms being arranged so that the columns of matter lie longitudinally of the cylinders. These features are not, however, essential to the invention, as the type-cylinders may be made of any desired length or circumference, and may be constructed so as to carry any desired number of forms which the character of the printed product may require, and the forms may, if preferred or found desirable, be arranged so that their columns will lie circumferentially instead of longitudinally of the cylinder, all as will be hereinafter more fully explained.

\V hen provided with type-cylinders of the size and carrying formsarranged in the manner just stated, the printing mechanisms hereinbefore described are capacitated to produce the following variety of products and at the fol-' lowing speeds; viz: two eight, ten, or twelve page papers at each revolution of the typecylinders, four six-page papers at each revo lution of the type-cylinders, or six four-page papers at each revolution of the type-cylinders.

In describing the operation of the printing mechanisms in producing these several products, the production of twelve page papers will be first considered.

. In this case both the main and supplement printing mechanisms are called into operation, and the gears 6867, or other mechanism by which the supplement-printing mechanism is driven, are so arranged that said mechanism will have the same surface-speed as the main mechanism. The forms for printing pages 12 1 will be placed upon the end of the type-cylinder 32 which is next to the side of the framework marked D, (see Fig. 2;) those for printing pages 11 2 upon the corresponding end of the cylinder 34, and those for printing pages 8 5 upon the end of the cylinder 50 which is next to the side of the frame-work marked H, while those for printing pages 10 3, 9 4, and 7 6 will be placed upon the opposite ends of the cylinders 32, 34, and 50, respectively. From this arrangement of the forms it results that after the main webs have been conducted through the printing mechanism and split into sections or narrow webs, as already described, the sides a of the webs A B will be printed with successions of pages 12 1, and the corresponding sides of the webs A B with successions of pages 10 3, while the sides I) of said webs will be respectively printed with successions of pages 11 2 and 9 4, all as shown in Figs. 6 and 7. After the web A has been split into two sections or narrow webs the web A is bent around the turning-bar 40 and led out of the machine at right angles to its former line of travel, it being thereby reversed or turned upside down, so as to present its side a uppermost, while the web A is bent around the turning-bar 41, it being also reversed, so as to present its side a uppermost, and also, by reason of the relation of the bars 40 41, brought directly underneath the section A, so that the two webs ALA' are laid one upon the other, both 'we'bs then passing to the roll 75, as shown in Fig. 5. After the web B has been split into two sections or narrow webs the web B is bent around the turning-bar 43 and led out of the machine at right angles to its former line of travel, being thereby reversed or turned upside down, so as to present its side b uppermost, while the web B is bent around the turning-bar 42, being thereby not only reversed or turned upside down, so as to present its side I) uppermost, but, by the relation of the turning-bars 42 43, brought directly over the web B, so that the two webs B B are laid one upon the other, both webs then passing to the roll 76. The turning and associating of the webs A A and B B also effect, in connection with registering rolls 105 and 107 108, the proper registration of the printed matter composing eight pages of the twelve-page products or papers, as is shown in Figs. 6, 7, 8, and 9.

From the arrangement of the forms upon the cylinder 50, which has been described, it results that after the web Chas been conducted through the printing mechanism and split into two sections or narrow webs, as already described, the side a of the web 0 and the side I) of the web 0 are printed with successions of pages 7 6, while the side I) of the web 0 and the side a of the web 0 are printed with successions of pages 8 5, as also shown in said figures.

It will be observed that the web 0 leaves its printing mechanism with its side at uppermost, and that when its sections are brought between the rolls 58 59 for association with the webs A A and B B, the web 0 under lies the webs A A", as in Fig. 6, and the web 0' overlies the webs B B, as in Fig. 9, so that when these three associated webs are passed together between cutting mechanism and severed on the dotted lines, and the severed sections are folded, as shown in Figs. 10,11, the result will be two twelve-page products or papers the pages of which will occur in their proper order.

From the foregoing it will be seen that when the machine is thus operated the product is two twelve-page papers at each revolution of the type-eylinders.

By reference to Figs. 2 and 3 it will be observed that the web-turners for operating upon the webs A and B are so arranged that the associated webs A A are carried over the roll 75 at the right-hand side of the delivery end of the machine, and that the associated webs B B" are carried under the roll 76 at the lefthand side of the delivery end of the machine, eieh set of associated webs taking up about one-half the length of its respective roll, from which it results that the associated webs pass side by side between the rolls 58 59, so that they may be conducted to and operated upon by a single folding delivery mechanism or by two mechanisms, if preferred.

XVhen it is desired to produce tenpage papers, or papers consisting of two four-page sheets with twopage supplements, the supple ment-printing mechanism will also be brought into use; but in this case the supplementprinting mechanism will be caused to run at one-half the surface-speed of the main printing mechanism, as will be hereinafter more fully explained. The forms upon the several type-cylinders will in this case be arranged in the order just described for the production of twelve-page papers, except that the forms upon the cylinder 50 for printing pages 7 and 8 will be removed and duplicate forms for printing pages 5 and 6 placed in their stead, while the forms upon the cylinders 32 and 34 for printing pages 9, 10, 11, and 12, will be removed and replaced by forms for printing pages 7, 8, 9, and 10. The side a of the webs A A will thus be printed with pages 10 1 and 8 3, and the side I) of said webs with pages 9 2 and 7 4.; and the sides a and b of the webs B B will. be printed, respectively, with the same pages. Both the webs will be split longitudinally, and the sections or narrow webs thus formed will be associated and delivered over the rolls 75 106 and 76 107 108 to and between the rolls 58 59, with their printed pages in proper register, precisely as has been described with reference to the production of twelve-page papers, and as shown in Figs. 12 and 13.

By reason of the duplication and arrangement of the forms upon the cylinder 50 the web 0 will be so printed that after it is split, as already described, the web 0 will be printed entirely with pages 5 upon its side a, and with pages 6 upon its side I), and the web 0 entirely with pages 6 upon its side a and with pages 5 upon its side I), as indicated in Figs. 12 and 13. The supplementweb C, after being split longitudinally by the slitter 96, has its sections C 0 led around a roll, 9, and forward side by side between the rolls 58 59, the web 0 being directly beneath the associated sections of the main web A, and the web G directly above the associated sections of the 9 main web B, as also shown in Figs. 12 and 13. The half or two-page sheets severed from the webs C O can now be readily associated and folded with the full or four-page sheets severed from the main webs, so that the whole will form the tcnpage product shown in Figs. 16 and 17.

From the foregoing it will be seen that the association of the sections of the main webs and the association therewith of the sections of the supplement-web is precisely the same in this case as in the case of the twclvepage product. In this case, however, the sheets severed from the supplement-web, instead of being full or four-page sheets and equal in length to those severed from the main webs,

are but half or two-page sheets, and conse-' quently of but half the length of the sheets severed from the main webs. It therefore becomes neccssary, as before stated, when this product is being produced,to reduce the speed of the supplement-printing mechanism to onehalf that of the main mechanism, so that the number of half-sheets produced by the former will be only equal to the number of pairs of full sheets produced by the latter. Thisis readily effected in the construction shown in the present case by shifting the gear 68, and substituting for the gear 67 anotherof twice the size, as indicated by dotted lines in Fig. 2. hen other means is employed for driving the supplement mechanism, the change of the speed can readily be effected in the same or an equivalent manner. Then the speed of the supplement-printing mechanism is thus reduced, the sections of the supplcmentwveb will pass between the rolls 58 59 atone-half the speed of the associated sections of the main webs, so that only a single half or two-page sheet will be delivered from each section of the supplement-web to each pair of full or four-page sheets from the associated sections of each main web. This difference in the speed of the supplement and main webs makes it necessary to provide means by which the supplement sheets after they are severed from the web can be accelerated to the speed of the main webs or the sheets severed therefrom, as indicated in Figs. 14 and'15. This may be effected by partially severing the supplementsheets, and then separating them in their line of travel by the well-known accelerated tapes; or it may be effected by mechanism such as shown in United States 'Letters Patent No. 225,746. This partial severance of the sheets of the supplement-web may be conveniently effected by means of a cutting-cylinder, as 8, (see Fig. 5,) arranged to act in conjunction with the impression-cylinder 52.

If the machine is providedwith the cuttingcylinder 8, its knife will of course be removed when twelve-page papers are-being produced.

From the foregoingit will be seen that when the machine is thus operated two ten-page papers are produced at each revolution of the type-cylinders. 7

When it is desired to produce eight-page papers, the main printing mechanism alone will be called into operation. In this case the forms upon the cylinders 32 and 34 will be arranged the same as when a ten-page paper is being produced, except that the forms for printing pages 7, 8, 9, and 10 will be removed and replaced by forms for printing pages 5, 6, 7, and 8. From this arrangement of the forms 7 it results that after the two webs have been conducted through the printing mechanism and split longitudinally, as already described, the sides a of the sections A B of the webs A B will be printed with successions of pages 8 1, while the sides a of the sections A B will be printed with successions of pages 6 3, the sides b of said sections being printed, respectively, with successions of pages 7 2 and 54, as shown in Figs. 18 and 19. After the two webs have been thus perfected and split the sections of each web will be turned, associated, and delivered over the rolls 75 105 106 and 76 107 108 to and between the rolls 58 59, precisely as has been described with reference to the production of ten and twelve page papers, and as also shown in Figs. 18 and 19, so that when the associated sections are divided on the dotted lines shown in said figures and folded, as in Figs. 22 and 23, eight page papers are produced; or the delivery may be accomplished (when it is desired that the product shall be in a fiat or unfolded condition) by leading the two sets of associated webs side by side to a single cutting mechanism and appropriate sheet-fliers.

From the foregoing it will be seen that one complete eight-page paper is printed upon each of I the webs A and B at each revolution of the type-cylinders, thus making the product of the machine two eight-page papers at each revolution of the type-cylinders.

When it is desired to produce six-page papers, or papers consisting of one full sheet with a half-sheet supplement, the supplementprinting mechanism will also be brought into use, and will be made to operate at the same speed as the main mechanism. The type-cylinder 32 will be provided at each end with forms for printing pages 6 1, and the typecylinder 34 will be provided at each end with forms for printing pages 5 2. From this it will result that the sides a of the two webs A and B will be printed with successions of pages 6 1, and their sides I) with successions of pages 5 2, as shown in Figs. 24 and 25. After being thus printed the two webs will be led around their respective turning-bars, 40 43, and outward above and below their respective rolls,7 5 76, the web A withits side a and the web B with its side b uppermost, and consequently with the heads of their pages pointing in opposite directions, as shown in said figures. In this case the slitters 6O 61 may be thrown out of operation, and the longitudinal splitting of the webs be effected after they have been severed transversely into sheets and after said sheets have received their first transverse fold. The type-cylinder of the supplement-printing mechanism will in this case, as in the case of the ten-page product, be provided with duplicate forms. These forms will, however, be arranged differently. The two forms for printing page 3 will be arranged end to end upon the cylinder with their heads pointing in one direction, and the twoforms for printing page 4 will be arranged by the side of those for printing page 3 with their heads pointing in the opposite direction, from which it will result that the supplementweb will be printed in the order shown in Figs. 24 and 25. After being thus printed the supplement-web will be led around the roll 9 and between the rolls 58 59, the section Opassing forward in register with the sections A B, and the section 0 in register with the sections A B of the main webs, as also shown in said figures. The slitter 96 may in this case also be thrown out of operation, so that theweb G will pass unsplit between the rolls 58 59, the splitting of the sheets being effected after they have been associated with the sheets from the main webs. The halfsheets severed from the web 0 will be alternately associated with the full sheets severed from the webs A B, as indicated in Figs. 26 and 27, the half-sheets bearing page 3 upon their upper sides being associated with the full sheets severed from the web A, and those bearing page 4 upon their upper sides with the full sheets severed from the web B, as also shown in said figures. This severing and association of the full and half sheets may be effected by means of a mechanism such as that shown in United States Letters Patent No. 255,723. If such a mechanism is used, the web A will be led, either directly from the roll 75, or after being conducted around the roll 58, to the upper pair of the cutting and folding cylinders shown in said patent. The web 13 will in like manner be led either directly from the roll 7 6, or after being conducted around the roll 59, to the lower pair of said cutting and folding cylinders, and the web C will be led either directly from the roll 95, or after being conducted between the rolls 58 59, to the cutting and carrying cylinders. If the webs are not split before passing to the cutting and folding mechanism, said mechanism must of course be provided with suitable slitters, which will operate to split the sheets after they have received their first transverse fold, thus producing the sixpage product shown in Figs. 28 and 29.

The association and folding of the sheets may be effected by any other suitable form of mechanism for the purpose. lVhen six-page papers are being produced the blade will of course be removed from the roll 8.

From the foregoing it will be seen that when the machine is thus operated four six-page papers are produced at each revolution of the typecylinders.

When it is desired to produce four-page papers, the typecylinders 32 34( will be provided with duplicate forms, the cylinder 32 being provided at each end with forms for printing pages 4 1, and the cylinder 34 at each end with forms for printing pages 3 2. From this arrangement of the forms it results that after the two webs have been conducted through the printing mechanism the side a of each. of the sections A A and B B will be printed with successions of pages 4 1, and the side I) of each of said sections with successions of pages 3 2, as shown in Figs. 30 and 31. In this case, as in the case of the production of six-page papers, the splitting of the webs may be omitted until after they have been severed into sheets and said sheets have received their first transverse fold. The web A will be led around the single turning bar 4-0 and the web B around the bar 48, which will bring the side a of the web A and the side I) of the web B uppermost as the webs pass laterally out of the machine, as also shown in the figures referred to. From the rolls 76 the webs may be led together to a suitable cutting and piling mechanism, or independently to suitable cutting and folding mechanisms, to be severed upon the dotted lines, folded transversely, and split longitudinally, so as to produce four page papers, as indicated in Figs. 32 and S3, or split longitudinally and piled in a flat condition, as may be preferred.

From the foregoing it will be seen that two four-page papers are produced from each of the main webs at each revolution of the typecylinders, making the entire product of the main mechanism four four-page papers at each revolution of the type-cylinders. If it should bedesired to produce this product with still greater rapidity, it may be done by bringing the supplementprinting mechanism into operation, in which case, instead of four, six i'our-page papers will be produced at each revolution ofthe type'eylinders. To do this the type-cylinder 50 will be provided at one end with forms for printing pages 4 1, and at its other end with forms for printing pages 3 2, the heads of all the forms pointing to the center of the cylinder, from which it will result that after the web 0 has been conducted through the printing mechanism in the manner already described, its respective sections will be printed with the same matter as the sections of the main webs. This web maybe then led out of the machine between the rolls 58 59 to a suitable cutting and piling or folding mechanism, and severed into sheets and folded or flown in the same manner as the sheets severed from the sections of the main webs. I11 this case the blade will be removed from the roll 8.

From the foregoing it will be seen that when the machine is thus operated two four-page papers are produced from each web at each revolution of the typecylinders, thus making the entire product of the machine six fourpage papers at each revolution of the type cylinders.

As shown in Figs. 1 to 5, and as thus far described, the main printing mechanism is capacitated to perfect and deliver but two webs. If, however, it should be desired to print from three rolls of paper, the type-cylinders 32 34: may each be provided with a. third impression-cylinder, as 82* 3. 2 and the main meehism with a third pair of turning-bars similar to the bars 40 41 and 42 43, so that instead of two, three main webs, as A B K, may be simultaneously perfected and delivered from the machine, as indicated by Fig. 34. When thus constructed. the product of the main mechanism would be three, eight, or sixfourpage papers at each revolution of the type cylinders.

Although, as herein shown, the type-cylinders are of sufficient length to receive two forms abreast, it is to be understood that the invention is not limited to this form of typecylinders. These cylinders may be of any desired length or circumference.

If it is desired to capacitate the machine to produce a product consisting of sixteen or more pages, the cylinders maybe of sufficient length to receive three or more forms abreast, in which case each cf the web turning or turning and associating devices will be provided with an extra turning bar or bars; or, if it is desired that the machine shall be capacitated to produce only a four or six page product, the type-cylinders may be of only sufficient length to receiveasinglc form. The diameter of the type-cylinders may also be increased from that shown, so that they will be of sufficient size to receive four or more forms cir eumfcrentially. In this case eight, ten, or twelve page products may be formed by associating the snccessively-produced sheets by any of the well-known forms of sheetcollecting mechanism.

The type-cylinders, instead of being entirely covered with forms, may be only partially covered, and be provided with an increased number of impression-cylinders and means by which each web will receive two or more impressions from each form at each revolution of the type-cylinders.

The supplement-printing mechanism and its web-turning devices are raised to the high position shown for the purpose of readily admitting the introduction of the roll 200 to a point between the cylinders of the main printing mechanism; but Where great compactness is required, it is obvious that. the printing oylinders 50 51 52 may be placed in a vertical stack near the side frame, their turning-bars then standing vertically. In this case the roll 200 may be supported at the side of the machine, and the web B be led laterally under the supplement-printing mechanism, and then be turned by a single turning-bar to be presented to'the printing mechanism, as shown in my application for Letters Patent filed May 16, 1883. "With this roll 200 in a frame on the floor, and the roll 100 likewise mounted, the two rolls would be so related to the roll carrying the web 0 that all might be watched and have their tensions regulated by a single attendant. This, as well as a delivery mechanism particularly adapted to deal with and deliver folded the large number of different products which this machine is capable of producing, will form the subject-matter of a future application for Letters Patent.

It will be observed that the position of the web turning and associating devices, and the arrangement of the columns of the forms, as herein described, has particular reference to the production of newspapers, which should receive their first fold in a direction transverse to the travel of the webs, which is the direction in which the printed columns run, and it will also be observed that, as herein described, the perfected webs, whether designed for a four, six, eight, ten, or twelve page paper, may be acted upon by one and the same set of folding and delivery mechanisms, and be properly folded or piled thereby. An equal or greater variety of products may be produced by arranging the forms so that the columns of matter lie circumferentially of the type-cylinders, and this, as well as a delivery mechanism adapted to receive and dispose of the webs, when printed with the forms in this position, will form the subject-matter of afuture application for Letters Patent.

If found desirable or necessary, suitable tapes may be provided for threading the machine, so that the webs may be automatically entered into and conducted through the machine at the commencement of the printing operation.

As hereinbefore described, the supplementprinting mechanism is one which prints both sides of its web from forms carried by one type-cylinder; but the invention contemplates the use of any form of web-printing mechanism capacitated to print upon both sides of a web,and any imposition of the forms which will produce the desired product, the forms on the type-cylinders of the main printing mechanism being arranged so as to properly combine therewith.

The form of the main printing mechanism may also be greatly modified from that hereinbefore described without departing from the invention. The main and supplement mechanisms may be substantial duplicates, each being capacitated to perfect a single web, and the printing-cy1inders of the two may be arranged parallel with instead of at right angles to each other, and yet preserve certain features of the invention. The diagrammatic view of Fig. 35 illustrates an organization of this character in which the main printing mechanism consists of two type-cylinders, 32 34, and two impression-cylinders, 31 35, the sup plementprinting mechanism being its substantial duplicate, and consisting, also, of two type-cylinders, 50 50*, and two impressioncylinders, 51 52, the cylinders of the two mechanisms being arranged parallel to each other, and the whole forming a machine simi' lar in its general organization to that shown in United States Letters Patent No. 195,115. In the present case, however, the type-cylinders of the two mechanisms are of the same size, and are provided, as in the organization hereinbefore described, with means by which they can be driven at the same or different surface-speed. This connecting mechanism may be of any suitable character; but as here shown consists of engaging-gears 67 68, secured to the shafts of the impressioncylinders 31 52. The webs A C, after being conducted through the printing mechanism, as indicated in the diagram, so as tobe printed upon their opposite sides, are led out at the end of the machine between the rolls 58 59, and thence con ducted to any suitable cutting and folding or flying mechanism, by which they may be severed into sheets and folded or piled, as de sired. If the printing mechanisms are capacitated to print a double-width web, slitters, as 60 96, will be provided, by which the webs may be split longitudinally into sections or narrow webs, and in such case the machine will also be provided with web-associating devices by which the sections of one or both of the webs may be associated. I

Assuming that the machine, thus organized, is capacitated to operate upon double-width webs, its operation will be as follows: To produce a twelve-page product, one of the webs will be of double width and the other of single width, and the two printing mechanisms will be run at the same surface-speed. Aft-er being printed the double-width web will be split longitudinally, and its sections will then be associated with each other and with the singleavidth web.

To produce a tenpage product, the web A
